Dell Monitor USB Ports Not Working: How to Fix

1. Rule Out Other Alternatives

First, we’re going to start with the obvious. Plug the device into a different USB port to see if the problem persists. This should tell you if it is a problem that comes from a single USB port or if all USB ports are affected.

You should also check the cable as well as the port on the peripheral you want to plugin. Make sure the port, as well as the cable, are in good condition. You can try switching cables or devices to narrow down the problem.

2. Ensure You’re Using the Right Port

It is handy to have knowledge of the functionality of the different types of USB ports on your computer. For example, some USB Type-C ports could be designated as data-only, which means you can only transfer data through but it cannot draw power. Meaning others could be for charging but won’t allow for file transfer. In addition, some ports might allow for USB Type-C cables and would require the use of converters.

3. Clean Out Debris

Just like smartphone charging ports, computer USB ports can be blocked with debris or grime. This prevents the cable from making a proper connection with the port. If you notice that the cable doesn’t plug all the way, it could be an indication that your computer needs some cleaning. You will need a flashlight as well as a toothpick.

Check if you can see dust or dirt in the port. Using the toothpick gently free up anything stuck inside.

4. Restart the Computer and Monitor

It’s possible that you’re just dealing with a computer glitch that can be fixed by simply restarting the computer. This internal error could occur when the computer’s RAM is used near its full capacity or you plugged in the cable while the computer is booting.

To fix;

For Windows

  • Click the Start menu > Power button > Restart.

For Mac

  • Click Apple > Restart.

5. Troubleshoot the USB Input to your System

If you’re still not able to fix the USB port, then you might want to check the USB Root Hub properties of your computer to confirm that Windows is not turning off the port to save power.

  • Open Device Manager, and click the arrow next to USB Serial Bus Controllers
  • At the bottom of the list will be about 2 to 10 USB Root Hubs
  • Right-click each hub, click Properties on the drop-down list, then click the Power Management Tab
  • Navigate to the “Allow the computer to turn off this device to save power box. Uncheck the box.
  • Repeat this process on all USB Root hubs
  • Reboot the computer and check to see if the USB Ports function properly.

For Windows

  • Go to Settings > Update & Security > Windows Update and click the Check for updates button

To update your USB driver automatically, you might want to use a software known as Driver Easy. This is a great option if you don’t have the computer skills to update your driver manually.
